    Skynet IA, the first of two Skynet military communications satellite built for the United Kingdom by the Philco-Ford Corporation, was launched from Cape Canaveral aboard a NASA Long Tank Thrust Augmented Thor/Delta (DSV-3L). The satellite was turned over to the United Kingdom on 30 January 1970, providing the United Kingdom with its first operational military communications satellite system. The Skynet satellites were designed to be usable with the Initial Defense Satellite Communication System (IDSCS) satellites of the United States. Over Indian Ocean. Military communications.

    The first of two communications satellites built for the North Atlantic Treaty Organization (NATO) by the Philco-Ford Corporation under a SAMSO contract was launched from Cape Canaveral aboard a NASA Long Tank Thrust Augmented Thor/ Delta booster. Inserted into synchronous orbit on 23 March, the satellite was turned over to the Supreme Headquarters Allied Forces Europe (SHAFE) on 19 May. Spacecraft engaged in practical applications and uses of space technology such as weather or communication (US Cat C). Positioned in geosynchronous orbit over the Atlantic Ocean at 18 deg W in 1970-1972; over the Americas at 100-110 deg W in 1977-1998 As of 3 September 2001 located at 101.97 deg W drifting at 0.023 deg E per day.

USAF Sat Cat: 4493 . COSPAR: 1970-062A. Apogee: 37,460 km (23,270 mi). Perigee: 278 km (172 mi). Inclination: 25.9000 deg. Period: 665.40 min.

    The second of two British Skynet I communication satellites (Skynet B) was launched from Cape Canaveral for U.S. Air Force and United Kingdom aboard a NASA Long Tank Thrust Augmented Thor/ Delta (DSV-3M) space booster. The spacecraft was placed in a transfer orbit prior to firing of the apogee kick motor that was to put it into a synchronous orbit over Kenya. Contact with Skynet B was lost during the firing of the apogee kick motor on 22 August and was not regained. The Skynet I satellites were part of the Initial Defense Satellite Communication System (TDSCS) program which was managed for the United Kingdom by SAMSO, with NASA providing launch vehicles and services. AKM failure left in unusable orbit. Spacecraft engaged in practical applications and uses of space technology such as weather or communication (US Cat C).

    The second NATO military communications satellite (NATO IIB) was launched by NASA aboard a Thrust Augmented Thor/Delta booster. Developed for NATO under SAMSO program management, the spacecraft was first placed in a transfer orbit and then moved into an acceptable synchronous orbit on 4 February. Although numerous difficulties were experienced prior to launch, the satellite achieved its stationary orbit and has performed successfully since then. Spacecraft engaged in practical applications and uses of space technology such as weather or communication (US Cat C). Positioned in geosynchronous orbit over the Atlantic Ocean at 26 deg W in 1971-1975?; over the Americas at 105 deg W in 1976-1983; over the Americas at 110 deg W in 1983; over the Americas at 105 deg W in 1983-1998 As of 5 September 2001 located at 104.88 deg W drifting at 0.004 deg W per day. As of 2007 Mar 9 located at 105.24W drifting at 0.007W degrees per day.
